Rope Cannon: Instantaneous displacement from rope causing large momentum which is able to be maintained with normal airborne movement.

[compsoter]

This bug allows you to gain large amounts of velocity though ropes "magnetism" through instantaneous displacement abilities/items. This bug has been reported before at:

Reproduction of the bug
Rope Cannon allows you to, with the displacement abilities or items below, gain massive amounts of momentum. To reproduce:

1. Have an item or ability that displaces you in position (E.g. Warp Stone, Magician’s 2)
2. Be on the rope and still.
3. Use a movement key (W, A, S, D or joystick input) and hold it for the duration of the bug.
4. Use the item or ability that displaces you
5. Exactly one game tick later (1/64th of a second), air dash. If done correctly, you should dash off the rope with large amounts of velocity (~5000 u/s).

Explanation

1. For one game tick from the initial displacement from the item/ability, you will be displaced normally.
2. On the next game tick, the game will attempt to move you back onto the rope in one game tick. This results in extremely high velocity traveling back. Normally, this is stopped by the rope and visually looks fine.
3. By dashing, you cancel going back onto the rope. This allows you to maintain the high velocity from traveling back onto the rope.

Clip
A slow motion clip in timescale 0.09 makes this easier to see. This clip uses Warp Stone to execute the bug:

The blue trail behind Warp Stone follows the general motion of the character; the trail goes in front, then moves back towards the rope and ultimately in the final trajectory.

Items/Abilities that can be used
The following items/abilities can be used to do this bug:

• Phantom Strike
• Warp Stone
• Sinclair's Spectral Assistant

One potential fix is to disable the use of these abilities while on a rope, like how Pocket's 2 results in a busy state notification while attempting to teleport.
